1. Is it in the Bible?

Yes. (84 references in the old testament--3 references in the new testament....

1Ti 3:15 But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.
Heb 10:21 And having an high priest over the house of God;
1Pe 4:17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?


2. What do we believe it means?

The house of God is the official meeting place of Christian believers. One of the most important jobs of Christians is to build this house. It is the place of worship. tithe and offerings build this house. The pastor ministers here.

3. What does it really mean?

These ideas are clearly all format he old testament. there are 3 verses that mention the "house of God" in the new testament, and this is often used as a "jumping off point" to verify that all these old testament requirements are necessary to the new covenant.

But it is clear that this new testament reference is speaking of the Christian home and the home meeting (how could it possibly be a reference to our idea of a church building--which did not come form hundreds of years in the future!). It is a reference tot he dwelling of God in man--a definitive new testament change...

"Howbeit the most High dwelleth not in temples made with hands; as saith the prophet," (Acts 7:48)

In the old covenant, the presence of God was behind the veil of the temple in Jerusalem (the house of God). this veil was torn from top to bottom while Jesus was on he cross and the Holy Spirit dwells in man.....

1Co 3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?

the believers' heart is now the "house of God", yet tradition tells us to function as if God lives in a building.
